Spinlock T25 – 4 Sheave Organiser (Symmetric and Asymmetric)
The Spinlock T25 4 Sheave Organiser provides a compact, efficient way to manage four lines on small and mid-sized yachts where deck space is limited. Built on the same 25 mm sheave platform as the rest of the T25 family, it offers excellent durability with a fibre-reinforced body and stainless steel wear strip.
The stainless steel unlinked base allows the organiser to sit cleanly on curved coachroof surfaces without stressing the mounting points. With Symmetric and Asymmetric layouts, the 4 Sheave model can be optimised for clean, low-friction line routing across a wide range of deck geometries.
Key Features
• Four 25 mm sheaves for multi-line organisation
• Strong fibre-reinforced construction
• Stainless steel wear strip protects lines and ensures smooth operation
• Unlinked stainless steel base adapts to curved mounting surfaces
• Symmetric and Asymmetric options for tailored lead angles
• Profile follows deck curvature for reduced friction
• Safe Working Load (SWL): 400 kg
Applications on Sailing Yachts
Well suited to yachts with several key controls led aft. Common examples include:
• Main, jib, and spinnaker halyards plus an outhaul
• Two reefing lines combined with vang and cunningham controls
• Running furling line take-offs alongside trimming controls
• Building multi-level systems using BE10 stacking options
